MLB notebook: Wainwright returns to St. Louis to have elbow tested
• The Cardinals are optimistic that the discomfort in ace Adam Wainwright's right elbow is not a serious problem. Wainwright returned to St. Louis on Wednesday for tests. The right-hander became the NL's first nine-game winner Tuesday night by pitching seven innings in a 1-0 win at Tampa Bay. Before Wednesday night's game against the Rays, Cardinals manager Mike Matheny said that everything the team had heard so far about Wainwright's elbow “has been positive.” Wainwright had elbow ligament replacement surgery in February 2011. Matheny said the discomfort was on the other side of the elbow. Wainwright is 9-3 with a 2.15 ERA in 14 starts for the NL champions.
• The White Sox signed Olympic speedskater Eddy Alvarez to a minor league deal as an infielder. The 24-year-old Alvarez was part of the relay team at the Sochi Olympics that won the silver medal in the 5,000-meter relay. He was a standout shortstop in high school in Miami.
• Rangers reliever Tanner Scheppers is going back on the disabled list because of right elbow inflammation less than a week after a return from the same problem.
• The Reds placed reliever Carlos Marmol on the restricted list after he left Triple-A Louisville without permission, CBS Sports reported. In three appearances with Louisville, Marmol posted a 7.36 ERA and 2.18 WHIP. He struck out six and walked six in 3 2⁄3 innings.
• The Red Sox signed 36-year-old outfielder Andres Torres to a minor league contract. Torres played in 103 games with the Giants in 2013 before having season-ending surgery on his left Achilles tendon.
