Cincinnati has lost four in a row and is 5-12 since opening the season by winning two of three from the Pirates. The Reds have five runs and 22 hits during the losing streak — 19 singles and two doubles.
Acquired from Colorado in an offseason trade, Joe went 3 for 3 with a walk and raising his batting average to .377. He was selected by the Pirates in the first round of the 2014 amateur draft and traded to Atlanta three years later for infielder-outfielder Sean Rodríguez.
Keller (2-0) gave up two runs and four hits in six innings with five strikeouts and one walk. He is unbeaten in five starts and pitched Pittsburgh’s 11th straight quality start.
Robert Stephenson, Colin Holderman and David Bednar finished a five-hitter, with Bednar pitching the ninth for his seventh save in eight chances.
With the score 2-2, Joe singled with one out in the sixth and advanced on a wild pitch by Derek Law (0-3) then took third on Jack Suwinski’s groundout. Shortstop Jose Barrero fumbled Mark Mathias’ grounder for an error that allowed Joe to score.
Carlos Santana added an RBI double in the seventh against Ian Gibaut.
Mathis hit a two-run single in the second off Graham Aschraft, who allowed three hits in five innings while striking out four and walking three. He gave up three runs over 19 innings in his first three starts this season.
Reds: There is no timetable for 1B Joey Votto (left rotator cuff surgery) to resume his rehab assignment with Triple-A Louisville that was paused last Saturday.
Pirates: Triple-A Indianapolis C Endy Rodríguez was placed on the 7-day IL with a strained right forearm and Low-A Bradenton INF Termarr Johnson (strained right hamstring) was activated from the 7-day IL. They are considered the organization’s top two prospects.
Reds RHP Luis Cessa (0-2, 13.50) is scheduled to face LHP Rich Hill (1-2, 5.57) on Saturday night in the third game of the four-game series.
