He does have the support of one of his chosen teammates, however, who hopes the impressive rookie might be able to take his spot.
Pineda will try to make his case when he takes the mound for the Mariners on Monday as they open a three-game road series against the Oakland Athletics.
Seattle (41-43) continues to get excellent starting pitching and after a particularly strong weekend series, it will try to take that momentum into a seven-game road trip before the All-Star break.
The Mariners won two of three against San Diego over the weekend, giving up just two runs. They won the finale 3-1 Sunday behind seven strong innings from Blake Beavan in his major league debut.
Seattle starters have an AL-leading 3.11 ERA this season and a 1.91 ERA in the last 16 games.
Pineda (7-5, 2.65 ERA) ranks sixth in the AL in ERA and is holding opponents to a .198 batting average.
Despite his credentials, Pineda wasn’t selected to the All-Star roster while teammates Felix Hernandez(notes) and closer Brandon League(notes) were picked. Hernandez, who is scheduled to pitch Sunday and therefore would be unavailable for the Midsummer Classic, put in his recommendation for Pineda.
“I’m a little surprised,” Hernandez told the Mariners’ official website. “He’s got pretty good numbers. … Maybe he can go there and pitch for me if I can’t pitch.”
Pineda, however, hasn’t been at his best lately. He allowed five runs and a season high-tying five walks over 6 1-3 innings Tuesday in a 5-4 loss to Atlanta. That was his third loss in four starts and left him with one win in his last seven.
The Mariners, though, haven’t provided him with much support, scoring 11 runs over his past seven outings.
He did pitch very well against Oakland on April 22, allowing five hits in six innings of a 4-0 win.
The Athletics (38-47) improved to 3-3 on their nine-game homestand with a 7-2 victory over Arizona on Sunday. Scott Sizemore(notes) had three hits, including a two-run homer in the sixth, and Conor Jackson(notes) also had a two-run shot in the inning.
Sizemore went 7 for 12 in the series, raising his average 31 points to .286.
“He’s a good on-base guy and hits the ball the other way,” manager Bob Melvin said. “He’s gained a lot of confidence and has become an everyday third baseman. He’s been a productive player.”
Oakland enters this series in last place in the AL West, 3 1/2 games behind Seattle, which has won four of the seven meetings overall this season and two of three on the road.
McCarthy, who has been on the disabled list due to a stress reaction in his throwing shoulder, is winless in his last seven starts. He gave up three runs in seven innings of a 4-3, 10-inning loss to Minnesota in his most recent appearance.
The right-hander is 1-3 with a 5.45 ERA in eight games - six starts - against the Mariners, but held them to one run and four hits over eight innings of a 1-0 loss April 21 at Safeco Field.
Oakland and Seattle rank 13th and 14th in the AL in runs per game with 3.5 and 3.4, respectively. Both have averaged 2.5 in their last 11.
