BOSTON -- It was only a matter of seconds before J.P. Crawford and Shed Long were greeted by excited teammates when they walked into the visitor’s clubhouse Friday afternoon at Fenway Park.

After a whirlwind day of travel that took them from Tacoma, Wash., in the morning across the country to Boston, both players were eager to get suited up for the evening matchup against the Red Sox.

“It’s truly a dream,” Long said.

Battling injuries to the infield, the Mariners called up the prospects from Triple-A and placed Dylan Moore (right wrist contusion) on the 10-day injured list. They also optioned right-hander Chasen Bradford to Tacoma in a corresponding move.

“The fact that he can’t throw the ball, it puts us in a tough spot,” acting manager Manny Acta said of Moore, adding, “I don’t think [he will miss more than 10 days], it’s just something that we couldn’t afford to wait and see how long it was going to take.”

The Mariners did receive a positive update on Dee Gordon, who was hit on the right wrist by J.A. Happ Thursday during a 3-1 loss to the Yankees. Gordon was out of the lineup on Friday.

“Great news,” Acta said. “Dee’s just day to day. Tests that they did to him, everything came out negative. So it’s very good news for us.”

Crawford started at shortstop and batted seventh on Friday. He was 2-for-4 with a pair of singles. Acta expects he and Long will remain in the lineup on Saturday to face Boston’s expected starter Rick Porcello.

“It felt good just to finally be back in front of all the fans, hearing all the cheering,” Crawford said. “My approach was good. Even my outs, they’re hard-hit balls.”

Seattle acquired Crawford last December via a trade with the Phillies that sent he and first baseman Carlos Santana (later dealt to the Indians) to the Pacific Northwest in exchange for shortstop Jean Segura and relievers Juan Nicasio and James Pazos. Crawford is an athletic shortstop who routinely graced the top of prospect lists before breaking in with Philadelphia, with whom he compiled a .692 OPS over 72 games from 2017-18. A former first-round Draft choice in '13, Crawford has reached base in a Pacific Coast League-best 31 straight games with Triple-A Tacoma and hit .319 overall on the season.

Crawford’s priority is staying healthy. On the field, he’s focused on scoring runs, turning double plays and staying away from chasing pitches out of the strike zone. He said he understands the decision to be sent to Triple-A, and he adopted a positive mindset to prove he could be at the Major League level.  

“Pouting’s not going to get your way up to the big leagues,” Crawford said. “Performing on the field and balling, that’s how you’re going to get up there. Turn that into positivity and it’ll turn out good.”

Long, 23, is Seattle’s No. 12 prospect and baseball’s No. 10 second-base prospect according to MLB Pipeline. He came to the Mariners in January as part of a three-team trade that sent pitcher Sonny Gray and lefty prospect Reiver Sanmartin to the Reds and a competitive balance Round A Draft pick and outfield prospect Josh Stowers to the Yankees. Long was hitting .276 with five doubles and four triples in 123 at-bats with Tacoma, appearing at second base, third base and left field defensively. The Mariners view the Jacksonville, Fla., native as a future starter at second base, as he’s shown a strong ability to drive the ball from the left side of the plate. Long’s defense at second is likely his biggest question mark.

“I don’t even know how to feel,” Long, who did not play Friday, said pregame. “It’s surreal. It’s such a dream. It’s like I worked all my life. This offseason I worked so hard because I said ‘I have to be in the big leagues this year.’ It’s kind of like, all that hard work is just paying off for me.”

After dashing out to a 13-2 record to begin the season, the Mariners have dropped one game below .500 (20-21). They currently sit second in the American League West, five games behind the Astros.
