Matt Cain will not start on Saturday against the Cardinals - MLB

The hope was that Giants starter Matt Cain, dealing with discomfort in his right hamstring, would be well enough to start on Saturday against the Cardinals. But as Henry Schulman of the San Francisco Chronicle reports, Cain has been scratched and Yusmeiro Petit will start in his place. Cain will go on the 15-day disabled list.

Schulman adds that there’s “nothing serious” with Cain; the Giants are simply being cautious. Cain hasn’t pitched since leaving after three no-hit innings against the Rockies on May 21.

Over eight starts spanning 46 2/3 innings, Cain has a 3.66 ERA with a 39/17 K/BB ratio.

ST. LOUIS — Miles Mikolas is sticking with the St. Louis Cardinals.

The right-hander signed a three-year, $55.75 million contract on Friday that will carry through the 2025 season.

The new deal replaces a $68 million, four-year contract signed in February 2019 that covered the 2020-23 seasons and was set to pay $15.75 million this year.

Mikolas will receive a $5 million signing bonus payable July 1 and will make $18.75 million in 2023 and $16 million in each of the following two seasons. Mikolas can earn a $250,000 bonus for winning a Cy Young Award, $50,000 for All-Star election or selection or winning a Gold Glove, $100,000 for League Championship Series MVP and $150,000 for World Series MVP.

Mikolas is scheduled to make the second opening-day start of his big league career next Thursday when the Cardinals host Toronto. Mikolas went 12-13 with a 3.29 ERA last season while helping St. Louis to the NL Central title.

“Miles stands among the top pitchers in the game today, and has continued to provide a steady presence for us both in the rotation and inside the clubhouse,” St. Louis general manager John Mozeliak said in a statement.

Mikolas is 45-40 with a 3.79 in 143 games with San Diego, Texas and St. Louis. He recently pitched six shutout innings in two appearances for the U.S. in the World Baseball Classic.
