by RotoWire Staff | RotoWire

Wendelken (1-0) earned the win Friday against the Astros. He allowed one unearned run on two hits and one walk while walking one in three innings.

Athletics' J.B. Wendelken: Strikes out side in loss
by RotoWire Staff | RotoWire

Wendelken fired a scoreless ninth inning in a loss to the Rockies on Tuesday, allowing a hit, uncorking a wild pitch and recording three strikeouts.

It was a bit of an eventful inning for the right-handed reliever, who ended up facing five hitters after allowing Daniel Murphy to reach safely by uncorking a wild pitch on a strikeout and then surrendering a double to Ryan McMahon. However, Wendelken impressively wiggled out of trouble with back-to-back whiffs to end the inning in what was only his second appearance of the season. The 27-year-old has been an effective middle-relief piece for manager Bob Melvin the last two seasons in particular, logging 49.1 innings across 40 appearances during that span.

Athletics' J.B. Wendelken: Highly regarded despite struggles
by RotoWire Staff | RotoWire

Wendelken generated a 6.75 ERA across 5.1 innings over five Cactus League appearances before spring training was suspended.

The 27-year-old right-hander was a solid component of the bullpen in the middle innings last season, posting a 3.58 ERA and 0.92 WHIP across 32.2 innings over 27 appearances. As his spring line indicates, Wendelken generally had a rough go of it in Cactus League play; however, that did little to dampen manager Bob Melvin's faith in the reliever, who boasts an impressive arsenal of pitches that includes a 95 mph fastball and a 94 mph sinker, Shayna Rubin of The Mercury News reports. "He's got plus stuff. He would have to pitch his way off the team," Melvin said. "He's showed, at times, here that he could be a back-end of the bullpen guy in some point in time."

by RotoWire Staff | RotoWire

The right-hander returned in the 11th, allowing a leadoff single to Bubba Starling. After intentionally walking Whit Merrifield, Wendelken loaded the bases by walking Adalberto Mondesi, but luckily, he struck out Jorge Soler to end the frame. A game-winning RBI double by Matt Canha in the bottom of the inning gifted Wendelken and the A's with a hard-fought win. Wendelken now owns a 3.66 ERA and 0.94 WHIP across 22 appearances this season.
