Oakland pitchers kept the Reds' bats mostly quiet until the bottom of the eighth inning, when Josh Satin, a non-roster invite, slugged a three-run homer off Brock Huntzinger to tie the game at 3-3. Satin added a game-winning single in the bottom of the ninth off Fernando Rodriguez, scoring Kristopher Negron to cap his four-RBI day.
Meanwhile, Reds starter Mike Leake gave up one earned run and four hits over his five innings with no walks and two strikeouts. It was the first run Leake surrendered in four starts during what's been a strong spring.
Oakland reached Leake with three hits in the top of the fourth inning, including a double to right-center field by Mark Canha that scored Marcus Semien. A second run was prevented from crossing on a perfectly executed relay from center fielder Skip Schumaker to shortstop Zack Cozart to catcher Tucker Barnhart, who tagged out Ike Davis.
"A few balls that I probably rushed got elevated a little bit," said Leake, who threw 75 pitches, including 10 in the bullpen after departing the game. "But all in all, I'm pretty happy. Just a couple of more [outings] to get back into it. So I'm trying to maximize the pitching."
Semien was 2-for-3 in the game to up his average to .308. For the Rule 5 selection Canha, who is trying to break camp with the A's, it was his third double in two games and his fourth over his last four games.
Oakland added a pair of two-out runs in the top of the seventh against reliever Pedro Villarreal. A pair of bench candidates, Tyler Ladendorf and Billy Burns, each hit RBI singles. Ladendorf lined his hit to center field while Burns reached on a blooper in front of left fielder Donald Lutz.
Up next: A's rotation candidate Chris Bassitt gets the start for a 1:05 p.m. PT matchup with the Indians on the road at Goodyear Ballpark on Monday. Most of the club's regulars, including Coco Crisp, Billy Butler, Ben Zobrist and Brett Lawrie, are expected to be in the starting lineup behind him. The game is available on an exclusive webcast and on MLB.TV.
