COLUMBUS, Ohio — If you were to count the total number of strikeouts Ohio State redshirt-junior left-hander Seth Lonsway totaled on Saturday, you'd likely need an abacus.

Ohio State (11-7) handled Indiana (11-6) to pick up a pair of wins Saturday afternoon first behind Lonsway’s 17-strikeout outing in Game 1. Lonsway's strikeout total was one shy of the Ohio State program record for punch outs in a seven-inning game, which came via Bill Gable in 1963.

Then, the Buckeyes saw five different players cross the plate in a crucial 5-2 Game 2 victory to sweep the doubleheader.

“Great team over there. I had to bring it, had to have my best stuff," Lonsway said. "I wanted to put my team in the best position to win the game. It was definitely a factor as far as preparing for this weekend and getting ready to play a good ball team."

Lonsway began his outing by striking out the first six batters - featuring an immaculate inning in which he threw all nine pitches for strikes in the second frame.

The Celina, Ohio, native set a new career-high in punch outs and was relentless in allowing just two hits and one walk, the latter of which a season-low. He pitched all seven innings; the first complete game thrown by an Ohio State starting pitcher this season.

The Buckeyes provided early run support with a solo home run in the first inning off the bat of junior shortstop Zach Dezenzo, then added two more by capitalizing on two Hoosiers errors in the second as five Buckeyes picked up a base hit.

Junior right-hander Jack Neely earned the start in Game 2 and went 4.2 innings, allowing two runs while piling seven strikeouts.

Dezenzo replicated his solo shot in the previous game with another in Game 2, sending a home run to the opposite field off Indiana freshman lefty Ty Bothwell. Sophomore right fielder Mitchell Okuley also swatted a solo home run and finished 2-3 with two RBIs.

"He was dominating. He threw the fastball for strikes and that makes them active," head coach Greg Beals said of Lonsway. "They have to respect both pitches. He’s throwing the fastball to get ahead and then they have to be active on that breaking ball, and that breaking ball is so good, especially today when it’s on. It was dominating, and that’s what it was today."

Lonsway may have foreshadowed his coming performance with the first batter of the ballgame. The lefty got Indiana leadoff junior designated hitter Drew Ashley to go down swinging, then retired the next five hitters on strikes.

Dezenzo crushed a pitch with a 2-0 count to center field, and the ball cleared the wall as the Buckeyes struck early.

Lonsway needed just nine pitches to get through the second inning - all of which went for strikes, resulting in the scarce immaculate inning.

"I felt confident that I was gonna command the ball well and pound the zone," Lonsway said. "I was constantly thinking getting strike one on the board."

The Buckeyes took advantage of two Hoosiers fielding errors to push across two runs in the bottom of the second. Senior second baseman Colton Bauer led off the inning with the lone hit of the frame, a triple to deep center field. Bauer and senior catcher Archer Brookman, who reached on the first error, both scored in the inning.

Brookman reached base again in the bottom of the fourth inning, drawing a walk on a full count after freshman left fielder Caden Kaiser got on base via Indiana’s fourth error in as many innings.

Back on the mound, the Hoosiers found their first hit with a leadoff single from redshirt-freshman right fielder Morgan Colopy. The Hoosiers, though, still went down on strikes as Lonsway’s first 10 outs of the ballgame came on whiffs.

Redshirt-senior first baseman Conner Pohl extended his team-leading home run count to five - although it didn't last through the end of the day - with a big fly in the bottom of the fifth, of which looked to get carried the wind blowing out to right field.

Lonsway punched out four of the final five Hoosiers to cap his complete-game masterpiece. He faced just three hitters over the minimum.

A little over 30 minutes later, the Buckeyes retook the field for a nine-inning contest to round out the doubleheader. While strikeouts were in abundance in the preceding contest, fly balls were aplenty in the later afternoon.

Just like he did in the first game, Dezenzo clobbered a solo home run in the first inning, this time to the opposite field. Sophomore right fielder Mitchell Okuley added an RBI single to extend the early lead to 2-0 three batters later after Indiana freshman left-hander Ty Bothwell issued back-to-back walks.

“I think the first inning we set the tone in both games today," Dezenzo said. "A couple of the home runs certainly helped that, I think. It was really good for us to come out hot of the gates for both games today and just carry it all the way through. We played a really good seven innings the first game and a full nine innings the second game, and that’s what we were trying to do."

Indiana got one run back on a solo shot by redshirt-senior shortstop Grant Macciocchi in the top of the fourth, but Okuley compensated with his fifth home run of the season in the bottom half to put the Buckeye lead at 3-1.

Junior third baseman Cole Barr drilled a solo home run into the trees beyond the left-field wall with two outs in the fifth inning to claw at the deficit, putting at 3-2.

Three-straight Buckeyes reached base to begin the bottom of the seventh as junior third baseman Nick Erwin connected with a single, senior designated hitter Sam Wilson drew a walk and Bauer was hit by a pitch.

Pohl connected on a ground ball up the middle, which skipped underneath the glove of Macciochi to allow two runs to come around and score - one of which earned - and put the lead at 5-2.

"Whenever you’re in a one-run game, things are a little tight. But when you can bring it to a little more that, you can definitely bring some weight off your shoulders," Okuley said. "I think that was huge, and later in the game when we got those two runs to make it a three-run game, that was also huge just to give us a little room."

For the second night in a row, the Buckeyes bullpen saw a lefty came in and provide valuable innings in long relief. Senior lefty and captain Griffan Smith made his third appearance of the season and tossed 3.1 innings of one-hit ball, striking out three.

Junior right-hander TJ Brock worked himself into a bases-loaded, two-out jam in the ninth, but got Barr to pop up to shortstop to end the threat and close the game, his sixth of the season.

Indiana saw six different players collect a hit, and Ashley went 1-3 with two stolen bases and was hit by a pitch.

Ohio State wraps its eight-game homestand with Indiana on Sunday with a 2:05 afternoon bill. Junior right-hander Will Pfennig will start his fourth game of the season, and will be contested by sophomore righty Gabe Bierman.

“Will’s gonna pitch with great tempo," Beals said. "He has a tendency to go too fast sometimes; it’s the right tempo for him and he needs to command his fastball. Even though it’s not a big fastball, he’s got great command of his fastball and if he can locate that fastball, I think he’ll have some success."
