Ravens cornerback Walker dies after dirt bike crash

Baltimore Ravens cornerback Tray Walker died Friday of injuries he suffered in a dirt bike crash in Miami.

Walker, 23, played one season in the NFL.

Miami-Dade police said Walker was riding a dirt bike with no lights and wearing dark clothing when he collided with a Ford Escape on Thursday night. He was taken to Jackson Memorial Hospital in critical condition.

In a letter to the team Friday before Walker died, Ravens coach John Harbaugh wrote: "That was the kind of phone call you never want get as a coach, as a parent, as a brother, as a friend. This shook me and all of us."

A fourth-round 2015 draft pick, Walker played in eight games last season, mostly on special teams.

• Cleveland cornerback Joe Haden underwent surgery on his ankle but is expected to recover in time for training camp in July.

• Indianapolis signed free-agent running back Jordan Todman, who was used sparingly by Pittsburgh last season.

• Kansas City signed Mississippi State track and field standout Tautvydas Kieras, even though the projected linebacker never played football. Kieras, a 6-foot-3, 271-pound Lithuanian, participated in Mississippi State's pro day and ran a 4.6-second 40-yard dash.

The uproar over Adam LaRoche's abrupt retirement from the Chicago White Sox turned ugly Friday, with ace Chris Sale accusing an executive vice president of lying to the team about why LaRoche's son needed to spend less time around the clubhouse.

LaRoche announced this week that he was leaving after VP Kenny Williams asked him to cut the amount of time his 14-year-old son, Drake, was spending with the White Sox. White Sox players were told three different stories by Williams about what happened, Sale said.

"We got boldfaced lied to by someone we're supposed to be able to trust," he said.

• Toronto pitcher Brad Penny said he has decided to retire after 14 seasons in the majors. Penny had a 10.29 ERA in four exhibition appearances.

Cal's Rachel Bootsma, a swimmer from Eden Prairie, won the 100 backstroke in 50.28 seconds at the NCAA championships in Atlanta. It's her third national title in the event.

Georgia led in the team standings with 285 points, and Cal stood second with 267.5.

Jason Day made it look easy Friday in the PGA Tour's Arnold Palmer Invitational with a 7-under 65 at Bay Hill in Orlando.

Day made a pair of long birdie putts and had stretched his lead to five shots when he finished his round in the morning at 13-under 131.

Henrik Stenson and Justin Rose, playing in the afternoon, made up ground but didn't catch up. Stenson shot 66 to close within two shots. Rose shot a 66 and was three behind.

• Woody Austin had six birdies in a seven-hole stretch and shot a 7-under 65 to take the first-round lead in the PGA Tour Champions' Tucson Conquistadores Classic.

Kelly Catlin of Arden Hills and team pursuit teammates Sarah Hammer, Chloe Dygert, Jennifer Valente and Ruth Winder will compete in the Rio Olympics, USA Cycling announced.

That group won a world championship and is a strong contender to win Olympic gold.

Hammer also will compete in the omnium.
