Lopez (0-4) took the loss Tuesday versus the Twins, allowing five runs on five hits and a walk while striking out nine over 4.1 innings of relief.

EDGE Analysis

The Athletics haven't announced their pitching plans for this series, aside from having Grant Holman serve as an opener Tuesday. That made this a somewhat unexpected outing for Lopez, who was pitching on regular rest after his short 1.2-inning start last Thursday against the Blue Jays. Lopez was tagged for three home runs Tuesday, all of which were solo shots. His workload was normal at 96 pitches (56 strikes), but the results continue to be troublesome for the southpaw, who is now at a 7.20 ERA, 1.75 WHIP and 26:10 K:BB across 20 innings through seven appearances (four starts). Lopez may still have a leg up on Osvaldo Bido for a spot in the rotation in the short term, as Bido worked as more of a traditional reliever following Lopez's bulk-relief outing.

Lopez (0-3) took the loss Thursday against the Blue Jays, allowing seven runs on six hits and a walk across 1.2 innings.

EDGE Analysis

Lopez set the Jays down in order in the first inning, but it was a different story in the second when the left-hander allowed six runs, with five coming on a pair of homers. Lopez's ERA is now up to 6.32 after Thursday's outing. He's posted a 1.85 WHIP and 17:11 K:BB across 15.2 innings. Lopez currently lines up for a home matchup with the Twins next week, should the A's choose to give him another shot in the rotation.

Lopez is slated to start Thursday's game against the Blue Jays in Toronto.

EDGE Analysis

Summoned from Triple-A Las Vegas last weekend to fill the opening in the rotation created by J.T. Ginn's (quadriceps) move to the injured list, Lopez stepped in and delivered a gem in his second start of the season for the Athletics. Though he ended up taking a loss, he limited the Phillies to one earned run on three hits and one walk while striking out eight over seven innings. The stellar performance will earn him at least one more start, and if Lopez can deliver another positive outing Thursday, he'll likely have a strong case for sticking around in the rotation over the struggling Gunnar Hoglund (5.13 ERA, 1.41 WHIP through five starts) once Ginn is back from the IL.

Lopez (0-2) allowed a run on three hits and a walk while striking out eight over seven innings, taking the loss versus the Phillies on Friday.

EDGE Analysis

Lopez deserved better, but he gave up the only run of the first seven innings of the game, a Trea Turner solo shot four pitches in. The Phillies tacked on three more runs in the ninth, and the Athletics' comeback push came up one run short, leaving Lopez with a hard-luck loss. This was his second start and fifth appearance of the season, and he threw 58 of 91 pitches for strikes in an impressive showing against a tough opponent. He has a 2.57 ERA despite a 1.57 WHIP and 17:8 K:BB through 14 innings in the majors this season. Lopez has a chance to make a positive impression while J.T. Ginn (quadriceps) is on the 15-day injured list. Lopez will look to repeat his performance from this start in his next outing, tentatively scheduled to be on the road in Toronto.

The Athletics recalled Lopez from Triple-A Las Vegas on Friday, Martin Gallegos of MLB.com reports.

EDGE Analysis

Lopez is expected to start Friday against the Phillies, as J.T. Ginn (quadriceps) recently landed on the 15-day injured list. Lopez made a spot start against the Rangers back on April 29, allowing three earned runs on six hits and four walks across 2.2 innings of work. He struck out four and took the loss. Lopez could make multiple starts for the Athletics while Ginn is sidelined.

Lopez is likely to start for the Athletics on Saturday versus the Phillies, Martin Gallegos of MLB.com reports.

EDGE Analysis

While he has not yet been officially recalled from Triple-A Las Vegas, Lopez already has a locker in the Athletics' clubhouse. The left-hander will be sliding into the rotation in place of the injured J.T. Ginn (quad). Lopez has made one start and three relief appearances at the big-league level this season, collecting a 3.86 ERA and 9:7 K:BB over seven innings. He could earn additional starts while Ginn recuperates.

The Athletics optioned Lopez to Triple-A Las Vegas on Wednesday.

EDGE Analysis

While making a spot start Tuesday against the Rangers, Lopez was touched up for three runs on six hits and four walks in 2.2 innings. He wasn't going to be available for a few days, so the Athletics will replace him on the 26-man active roster with a fresh bullpen arm in Carlos Duran, who was called up from Triple-A.

Lopez (0-1) took the loss Tuesday against the Rangers after allowing three runs on six hits and four walks in 2.2 innings. He struck out four.

EDGE Analysis

Although Lopez was able to escape a bases-loaded jam in the first inning during his first start of the season, he was already up to 37 pitches after one frame. He also allowed a leadoff baserunner in each of his three innings of work Tuesday. The left-hander has a 3.86 ERA over seven innings so far, but his 9:7 K:BB and 2.57 WHIP are major causes for concern. It remains to be seen if Lopez will get another chance to start for the Athletics in the absence of J.T. Ginn (elbow), but the former's next appearance tentatively lines up for this weekend in a soft matchup against Miami.

Lopez will serve as the opening pitcher for Tuesday's game against the Rangers, Jessica Kleinschmidt of Baseball America reports.

EDGE Analysis

Lopez hasn't recorded more than five outs in an appearance this year, so he'll presumably be asked to work the first inning or so before giving way to a bulk reliever. The southpaw has yet to allow an earned run over 4.1 frames this season.

The Athletics recalled Lopez from Triple-A Las Vegas on Saturday.

EDGE Analysis

Just three days after being sent to Triple-A, Lopez will return to the big club Saturday to replace J.T. Ginn (elbow) on the active roster. The 27-year-old Lopez has punched out five batters and walked three over 4.1 shutout innings in the majors this season and will likely return to a middle-relief role.
