NO WORD YET

The Dodgers are still waiting for definitive word on how long closer Kenley Jansen might be out because of an irregular heartbeat. He was put on the 10-day disabled list Friday and manager Dave Roberts wasn't sure if his absence would be 10 days or possibly even closer to a month — like it was when the right-hander went on the DL for the same thing seven years ago.

"I'm hoping as soon as I can to get something, just for my peace of mind, the guys on the field — our peace of mind," Roberts said. "His health is most important. Whatever they have to do, the doctors have to do, to protect him."

The 30-year-old Jansen was tied for the NL lead with 32 saves. In his absence, Roberts will use a closer-by-committee approach.

ARENADO AILING

The Rockies will see how star third baseman Nolan Arenado is feeling, a day after his early exit during a 5-4 win over the Dodgers at Coors Field. The Gold Glover has been bothered by a sore shoulder for a week and tweaked it while turning a double play in the third inning. He was covering second base on a play that was scored 3-5-3.

"After it, I had trouble throwing," he said. "It hurt too much to let it fly after that."

HOW MANY?

J.D. Martinez has become the first major leaguer this season to top the century mark in RBIs — the Boston bopper is at 101 after driving in two more Friday night at Baltimore.

Martinez set a career high with 104 RBIs last year while playing for Detroit and Arizona. The AL East-leading Red Sox have 45 games left for him to keep piling up the total.

SEATTLE SURGE

After beating Astros aces Justin Verlander and Gerrit Cole on consecutive nights, the Seattle Mariners try to keep up their run at Minute Maid Park. Next, they'll face Charlie Morton (12-2, 2.81 ERA). Wade LeBlanc (6-2, 3.81) starts for Seattle, which trails Houston by six games in the AL West.

DOING DAMAGE

Ronald Guzman has been a one-man wrecking crew against the Yankees this season. The Texas rookie has hit six home runs in 15 at-bats vs. New York — and only six more in 263 at-bats against everyone else. The 23-year-old Guzman homered three times Friday night in the Bronx, making him the first rookie to hit three in a game against the Yankees.

NICE START

Cedric Mullins became the first Baltimore player to get three hits in his major league debut, also scoring three runs and driving in a pair during a 19-12 loss Friday night to Boston. The 23-year-old Mullins doubled twice while batting ninth and playing center field.

All-Star Adam Jones has played center field since his arrival at Camden Yards in 2008. But the 33-year-old will finish the season in right field as the last-place Orioles look to next season and beyond. "This is about the future going forward," manager Buck Showalter said.

KEEP TRYING

Blue Jays right-hander Sam Gaviglio is 0-4 in 13 starts since winning in late May at Philadelphia. He hopes to end that skid when he pitches at home against Tampa Bay.
