Lopez (elbow) is making good progress and has an outside chance of pitching in MLB before the season ends, Martin Gallegos of MLB.com reports.

EDGE Analysis

Lopez landed on the injured list Aug. 26 with a left elbow flexor strain, just two days after giving up nine runs in a disastrous start against the Mariners. Prior to that outing, the southpaw had been effective, recording a 3.28 ERA and 1.17 WHIP across 20 appearances (16 starts) and 90.2 innings. The Athletics aren't in a position to rush him back without playoff pressure, but the positive reports on his recovery are at least encouraging for a possible return.

The Athletics placed Lopez on the 15-day injured list Tuesday with a left elbow flexor strain.

EDGE Analysis

Lopez's strained elbow played a factor in his performance Sunday against the Mariners, which saw him cough up nine earned runs in only two innings. The A's will keep him shut down for a period of time before starting up a throwing program, though they are still optimistic that the 27-year-old southpaw will make it back before the end of the year. Mason Barnett was selected from Triple-A Las Vegas to take Lopez's place on the active roster, but the team hasn't yet announced who will claim the open rotation spot.

The Athletics have shut Lopez down from throwing due to a Grade 1 flexor strain in his left arm, Martin Gallegos of MLB.com reports.

EDGE Analysis

Lopez tossed just 65 pitches in his start against the Mariners on Sunday, giving up nine earned runs on six hits and six walks while striking out two across two innings. Manager Mark Kotsay noted Monday that a roster move will be made Tuesday to officially add Lopez to the 15-day injured list, though the club is hopeful that he'll be able to return at some point before the end of the season, even if it means he's working in a bullpen role, according to Gallegos. Joey Estes and Osvaldo Bido will be candidates to enter the Athletics' rotation in Lopez's absence.

Lopez is dealing with left forearm tightness following Sunday's 11-4 loss to the Mariners, Martin Gallegos of MLB.com reports.

EDGE Analysis

Lopez was tagged with nine runs on six hits and six walks while striking out two batters over two innings against Seattle. The left-hander had given up 10 total runs (nine earned) over his last seven starts prior to Sunday's contest, so it seems to make sense that he wasn't operating at 100 percent versus the Mariners. Manager Mark Kotsay said that Lopez will be re-evaluated Monday, but considering the early diagnosis, there's some concern over the left-hander's availability moving forward.

Lopez (7-6) yielded three runs (two earned) on four hits and a walk over six innings Tuesday, striking out eight and earning a win over the Twins.

EDGE Analysis

Lopez extended his scoreless streak to 25 frames before Matt Wallner knocked an RBI double in the second inning. Brooks Lee and Ryan Jeffers later knocked solo homers in the fourth and fifth innings, respectively. Despite that, Lopez earned his fourth consecutive win and racked up eight punchouts. He's produced a 27:1 K:BB over his last three outings, improving his season K:BB to 111:31. Lopez has registered a 0.60 ERA over his last five starts, dropping his season ERA from 4.60 to 3.28 in the process. He's lined up to take the mound in Seattle this weekend.

Lopez (6-6) allowed four hits, struck out nine batters and walked none over seven shutout innings to earn the win Tuesday over the Rays.

EDGE Analysis

Lopez continues to look like the Athletics' best starter lately. Over his last four outings, he hasn't given up a run while posting a 28:6 K:BB across 24 innings in that impressive stretch. He won't keep this up forever, but his strong second half is showing serious developmental progress. He's now at a 3.30 ERA, 1.19 WHIP and 103:30 K:BB through 84.2 innings over 19 appearances (15 starts) this season. Lopez will look to keep rolling in his next outing, which is projected to be on the road in Minnesota.

Lopez (5-6) earned the win Thursday over the Nationals, allowing only three hits and no walks over 7.2 scoreless innings. He struck out 10.

EDGE Analysis

It was a stellar performance from Lopez, who set a new season high with his 10 punchouts. The left-hander has delivered 17 consecutive scoreless innings over his last three outings after struggling to a 7.13 ERA in his previous four starts. Overall, Lopez's ERA is down to 3.59 on the year with a 1.25 WHIP and 94:30 K:BB across 77.2 innings. Lopez is currently in line for a home matchup with the Rays his next time out.

Lopez (4-6) allowed five hits and two walks while striking out five over five scoreless innings to earn the win over the Diamondbacks on Friday.

EDGE Analysis

Lopez wasn't efficient -- he needed 95 pitches (63 strikes) to get through his five frames -- but he got the job done against a depleted Arizona lineup. The southpaw had a middling July, posting a 5.30 ERA in 18.2 innings across four starts, though he has tossed 9.1 scoreless frames over his last two outings. For the season, Lopez has a 3.99 ERA, 1.34 WHIP and 84:30 K:BB through 70 innings over 17 appearances (13 starts), which could make him a serviceable option in deeper mixed and AL-only formats. He's lined up for a favorable road start versus the Nationals next week.

Lopez did not factor into the decision in Saturday's game against the Astros, allowing two hits and four walks while striking out four across 4.1 innings.

EDGE Analysis

Lopez allowed two baserunners in each of the first two innings of Saturday's start but managed to escape without yielding a run. He finished his outing with 10 whiffs, but he couldn't make it through five innings to be in line for the win after tossing 95 pitches (53 strikes). Lopez sits at a 4.29 ERA and 1.34 WHIP across 65 innings heading into his next start, tentatively slated for next weekend at home against the Diamondbacks.

Lopez (3-6) took the loss against Texas on Monday, allowing five runs on four hits and three walks while striking out six batters over five innings.

EDGE Analysis

Lopez was hurt by the long ball in the defeat, allowing a solo blast and a three-run shot to account for most of the damage against him. The five runs were the most he's given up since June 3 (a span of eight starts). Lopez did at least manage to complete five innings -- just the second time he's done so over his past four outings -- but he's faded after giving up just one run over 23 innings during a four-game span in June. In his four starts since that impressive stretch, Lopez has posted a 7.13 ERA, 1.42 WHIP and 20:7 K:BB over 17.2 frames.
