Walker Buehler: Everything you need to know

Buehler (2-2) allowed four runs on seven hits and struck out five without walking a batter over 5.1 innings to earn the win over the Giants on Tuesday. Buehler worked into the sixth inning for just the second time this season. He's allowed exactly four runs in all three of his road starts, but the Padres gave him enough help Tuesday to get the win. This was also just the second time he's issued zero walks in a start this year. The 31-year-old is at a 5.64 ERA, 1.52 WHIP and 29:12 K:BB through 30.1 innings over seven starts. Buehler is lined up for a home start versus the Cardinals over the weekend.

Buehler tossed 4.2 innings against the Cubs on Tuesday, allowing two runs on three hits and three walks while striking out four batters in a no-decision. Buehler didn't give up a destructive number of runs, but he tossed just 48 of 92 pitches for strikes and was pulled before he could complete five innings. It was the second straight start and fourth time through six outings this season that the veteran righty has been unable to go five frames. Buehler has pitched to a poor 5.40 ERA and 1.56 WHIP with a 24:12 K:BB through 25 innings, but he's remained in the injury-plagued Padres rotation. With that said, San Diego signed Lucas Giolito to a contract last week, and Griffin Canning (Achilles) is in the midst of a rehab stint, so it's fair to wonder if Buehler will be able to hold on to his starting spot when those hurlers join the big-league club.

Buehler (1-2) allowed four runs on eight hits and three walks while striking out two over 2.2 innings to take the loss versus the Rockies on Wednesday. Buehler's pitch count got up early -- he ended at 82 pitches (47 strikes). That's the third time in five starts where he's failed to complete five innings, and he's fallen short of three frames in two of those games. The right-hander is sporting an ugly 5.75 ERA, 1.62 WHIP and 20:9 K:BB across 20.1 innings so far. Buehler is likely to remain at the back end of the Padres' rotation for now, though he could be pressured once Lucas Giolito, who signed a one-year contract with San Diego on Wednesday, is up to speed. Buehler's tentatively lined up to make his next start at home versus the Cubs.
