CHICAGO (Interstat) — Nathanial Lowe and JJ Bleday each homered for Cincinnati, but the Chicago Cubs walked off with a 3-2 victory in 10 innings Tuesday night at Wrigley Field, extending their winning streak over the Reds to two games.

The Cubs improved to 24-12, while the Reds dropped to 20-16. Ryan Rolison earned the win in relief, improving to 3-0, and Sam Moll took the loss, falling to 1-2.

The game was a pitchers’ duel early, with both starters effective. Cincinnati grabbed the lead in the first inning. After TJ Friedl flied out, Bleday launched a solo home run to right-center field, his fourth of the season. The Reds added to their lead in the sixth when Lowe connected for a solo shot to right field, his sixth homer of the year.

Chicago did not score until the seventh. With two outs, Pete Crow-Armstrong singled and Nico Hoerner walked. Alex Bregman followed with a single to left, scoring Crow-Armstrong and cutting the deficit to 2-1. The rally ended when Ian Happ struck out.

The Cubs tied the game in the eighth. After Dansby Swanson lined out, Michael Busch led off with a solo home run to right-center, his third of the season. Two batters later, Miguel Amaya reached on a fielding error by left fielder TJ Friedl, but Crow-Armstrong grounded out to end the inning.

Both teams had chances in the ninth. Reds reliever Emilio Pagán worked a scoreless inning, allowing no hits. Cubs reliever Jacob Webb also held Cincinnati scoreless, stranding a Tyler Stephenson single.

The game went to extra innings. In the top of the 10th, Reds batters Ke’Bryan Hayes and Friedl struck out, and Dane Myers walked. Elly De La Cruz grounded out to second base, ending the threat.

In the bottom of the 10th, Chicago put the game away. Michael Busch singled to center off Moll, driving in Swanson from third base. Swanson had been placed at second base as the automatic runner under MLB’s extra-inning rule. The hit gave the Cubs a 3-2 victory and capped a comeback that saw them erase a two-run deficit.

Cincinnati finished with six hits, led by Lowe’s two-hit game that included the home run and an RBI. Spencer Steer singled and Stephenson added a single. De La Cruz, Matt McLain, Ke’Bryan Hayes and Friedl were all hitless. Tony Santillan worked one inning, allowing one earned run on one hit with a strikeout.

Rolison pitched the 10th for the win.

The Reds had another scoring opportunity in the fourth inning. After Sal Stewart grounded out, Lowe singled and Steer singled, putting runners on first and second. Stephenson walked to load the bases with one out. But Matt McLain flied out to left, and Ke’Bryan Hayes grounded out to end the inning.

Chicago threatened in the fifth. Michael Busch singled, and Miguel Amaya walked. But Crow-Armstrong struck out and Hoerner lined out to center.

In the sixth, the Cubs loaded the bases with two outs on a walk to Seiya Suzuki, a single by Swanson and a walk to Busch. Connor Phillips induced a forceout from Moisés Ballesteros to end the inning.

The Reds had another chance in the eighth when Elly De La Cruz reached on a fielding error by Busch at first base. But Stewart struck out, and the inning ended.

Chicago’s bullpen retired the first two batters in the ninth before Stephenson singled. McLain lined out to left to send the game to extra innings.
