The Miami Marlins on Saturday activated right-hander Henderson Alvarez from the 15-day disabled list and he is scheduled to start Saturday night against the Arizona Diamondbacks.
MLB.com had the roster move on its transactions page.
Alvarez was placed on the DL in late July because of inflammation in his shoulder, but wound up missing just two starts.
To make room for Alvarez on the roster, the Marlins optioned right-hander Anthony DeSclafani to Triple-A New Orleans.
Alvarez earned his first All-Star berth this season and is 8-5 with a 2.48 ERA and 1.220 WHIP in 22 starts covering 137.2 innings.
His ERA is fifth-best in the National League and he leads all of baseball with his three shutouts this season.
In his first season with the Marlins, Alvarez was 5-6 with a .359 ERA and 1.140 WHIP, but was limited to 17 starts and 102.2 innings because of the same inflammation issue in his shoulder.
He bounced back to throw a no-hitter on Sept. 29 last season in a game Miami won in walk-off fashion, with the game’s only run scoring with two outs in the bottom of the ninth on a wild pitch by Tigers reliever Luke Putkonen.
DiSclafani had has been up and down with the Marlins this season and had last been recalled on Aug. 8. He is 1-2 with a 6.84 ERA and 1.405 WHIP in seven appearances, five of them starts, for Miami, with 20 strikeouts in 26.1 innings. He was also acquired from Toronto in November 2012.
