Rapid Reaction: Athletics 5, Rangers 1

OAKLAND, Calif. -- The Texas Rangers' four-game winning streak came to an end Monday night, when they fell 5-1 to the Oakland Athletics in the opener of a three-game series against the defending American League West champions.

Rough outing: Rangers right-hander Justin Grimm, who was named the American League Rookie of the Month for April, fell to 0-3 in May, taking the loss Monday. Grimm (2-3) gave up five runs on seven hits -- two of them home runs -- over just five innings. He struck out three and walked two. Grimm pitched a scoreless first, but he gave up three singles and two runs in the second, then two runs in the third as A's outfielders Yoenis Cespedes and Brandon Moss crushed back-to-back home runs to center field. Cespedes lined a high fastball just over the 400-foot mark, and Moss hit a high, inside fastball higher and deeper to center.

Moreland goes deep: Rangers first baseman Mitch Moreland hit his seventh home run of the season, a solo shot to deep right field off A's starter A.J. Griffin in the top of the second inning. Moreland extended his hitting streak to a season-high six games. Moreland's home run was his fourth in his past eight games, and he made Griffin pay for throwing a belt-high fastball down the middle with a 2-2 count.

Struggles at the plate: One day after scoring 12 runs and pounding out 17 hits in a win over the Houston Astros, the Rangers made little noise at the plate outside of Moreland's blast. Griffin held them to six hits -- five of them singles -- over seven innings and struck out eight. He kept the Rangers off balance with his big, slow curveball, and struck out Elvis Andrus twice looking. Ian Kinsler and Moreland also fanned looking. None of them appeared happy with home plate umpire Lance Barksdale's strike zone. In the eighth, A's left-handed reliever Sean Doolittle struck out Geovany Soto looking, Jeff Baker swinging and Craig Gentry looking. Texas finished with just seven hits.

Up next: The Rangers face the A's in the second game of their three-game set Tuesday night at 9:05 p.m. CT on FSSW and ESPN 103.3 and 1540. Texas will send left-hander Derek Holland to the mound against A's right-hander Bartolo Colon.
