Marlins hurler Anthony DeSclafani would not mind turning back the clock. Since giving up only two earned runs in six innings in his Major League debut on May 14, he has surrendered 16 earned runs in 15 1/3 innings since.
He has given up six hits or more in all four of his outings, but he has been unable to limit the damage as effectively in his past three turns as he did during that first start. The Mets tagged him for a career-worst seven runs on seven hits in 3 2/3 frames on June 22.
"That's not the start I wanted," DeSclafani said after the loss. "You're not going to get the results you want pitching like that. I didn't give my team a chance to get outs or get a win. That falls on me, for sure. Being up here, you have to be consistent. That's pitch to pitch, locating all your pitches and keeping hitters off balance. If I want to have success up here, that's what I have to do -- locate and get ahead, get more balls on the ground, and I didn't do that today."
DeSclafani's life will not get any easier as the A's lead the Majors with 398 runs scored this season. Oakland has been especially productive as of late, winning eight of its last 11 games and averaging 5.6 runs per contest during that stretch.
The A's have scored fewer than four runs only twice during this current run.
The Marlins will also have to contend with Jesse Chavez, who gave up just one earned run over 13 innings in back-to-back starts against the Yankees and the Red Sox. His 2.71 ERA in 15 starts this season is astounding given his previous big league experience.
Entering this season, Chavez had made as many starts (four) since making his Major League debut in 2008 as DeSclafani has made this season alone. Chavez, who took a no-hitter into the sixth against Boston on June 21, has yielded two earned runs or fewer in 11 of his starts this season.
Oakland has been happy to see Chavez return to form in his recent gems against the Yankees and the Red Sox after going 1-3 and giving up 14 runs (11 earned) in a four-start stretch from May 24 to June 9.
"Today was, I thought, similar to what we were seeing real early in the season," A's manager Bob Melvin said after Chavez stifled New York on June 15. "You could tell right away he was on it pretty good, cutter to both sides of the plate, good curveball to create a gap between the hard stuff and the offspeed stuff, threw a few good changeups.
"It's not like he was pitching poorly, but this is the type of outing we were seeing earlier in the year when he was really knifing through teams and cutting through them very quickly."
Athletics: Producing in a pinch
• Although playing in the American League does not require much use for pinch-hitters, Oakland is in good shape as it heads to Marlins Park. A's pinch-hitters are 9 for their last 20 (.450) with two doubles, two homers, eight RBIs and two walks.
Oakland's pinch-hitters are batting .284 (19-for-67) with three homers, 15 RBIs and 14 walks this season. The Athletics' pinch-hit walk total ranks third in the Majors.
Marlins: Stanton chasing franchise history
• Giancarlo Stanton homered in Thursday night's 5-3, 14-inning loss to the Phillies, giving him 21 home runs and 59 RBIs. He is one of six Marlins to hit 20 or more homers and notch 50 or more RBIs before the All-Star break. Mike Lowell was the last one to do it, accomplishing the feat both in 2003 and '04. Lowell's 28 home runs and 76 RBIs in 93 games prior to the 2003 All-Star break are a franchise record.
Stanton leads the NL and ranks among the top five in the Majors in both categories this season.
• The A's own the best record in the Majors since the beginning of the 2012 season at 238-164.
• The Marlins have won 13 of their last 14 Interleague games.
