MIAMI -- Following Saturday's second 14-inning game in three days, a 7-6 loss to the A's, Marlins manager Mike Redmond announced the demotions of outfielder Jake Marisnick and starter Anthony DeSclafani.
Christian Yelich will return to the lineup on Sunday, and to accommodate him, the Marlins had to option outfielder Marisnick to Triple-A New Orleans. DeSclafani will also return to New Orleans, but a corresponding move has not been announced.
Yelich, who went 1-for-9 with four RBIs, five strikeouts and a homer in two rehab starts with New Orleans, has been on the 15-day disabled list since June 16. He suffered a lower back strain in the first inning on June 13 against the Pirates, when he fielded a leadoff single.
The 22-year-old is batting .259 with a .342 on-base percentage with the Marlins this season.
DeSclafani made three starts after he was recalled from New Orleans on June 16. He went 0-1 with a 9.00 ERA and struck out eight while allowing a .346 average against him.
Since the bullpen has thrown 20-plus innings in the last three days, a reliever is expected to be recalled in DeSclafani's stead.
Marisnick, who joined DeSclafani in the flurry of nine roster moves made on June 16, played in 13 games, including 10 starts. While he impressed with his arm, the center fielder's bat lacked luster as he hit just .170 and struck out 18 times.
