Velazquez is hitting .500 with four home runs and a 4:4 K:BB in six games since getting promoted to Double-A Akron on Aug. 11.

Velazquez had been dialed in at High-A Lake County prior to his promotion, as he slashed .336/.417/.598 with seven home runs and a 14.4 percent strikeout rate in his final 31 games for the Captains. The lefty-hitting first baseman/corner outfielder turned 20 in May, so he's young for Double-A but has been the best hitter at the level since arriving there last week.

Solano will start at first base and bat sixth in Wednesday's game against the Phillies.

After serving as a fairly consistent presence in the lineup against left-handed pitching during the first half of the season, Solano will be included in the starting nine for the fifth time since the All-Star break. His downturn in playing time coincides with the trade-deadline acquisition of Josh Naylor, who bats from the left side of the plate but has produced well enough against southpaws this season (98 wRC+ in 158 plate appearances) to avoid being platooned. However, with the Mariners wrapping up their series in Philadelphia with a day game after a night game and with a southpaw (Jesus Luzardo) on the bump for the Phillies, Seattle manager Dan Wilson likely viewed it as an opportune time to give Naylor a break.

Naylor is not in the lineup for Wednesday's game in Philadelphia.

The left-handed-hitting Naylor will get a day off as the Phillies send southpaw Jesus Luzardo to the bump. Donovan Solano will handle first base and bat sixth for Seattle.

Guerrero (hamstring) remains out of the lineup for Wednesday's game in Pittsburgh.

Guerrero will sit out for a second straight game after he tweaked his left hamstring in Monday's 5-2 loss. He's been diagnosed merely with inflammation rather than a strain, so Guerrero could be ready to play Friday in Miami after the Blue Jays' team off day Thursday. Ty France will again cover first base for Toronto in Wednesday's series finale.

Aranda (wrist) is scheduled to have X-rays on Wednesday, with manager Kevin Cash noting that the tests "will provide a little more clarity" on the first baseman's status moving forward, Marc Topkin of the Tampa Bay Times reports.

Cash added that Aranda has been recovering well thus far from his fractured left wrist, an injury he sustained while applying a tag in a July 31 game against the Yankees. If the X-rays show improved healing for Aranda, the Rays should have a better idea regarding when he might be ready to resume baseball activities. Aranda won't be immediately thrust back into action once he's cleared to swing the bat and start fielding grounders, however, so his return from the 10-day injured list is unlikely to come until early September in a best-case scenario.

Lowe started at designated hitter and went 1-for-4 with a home run and two RBI in Tuesday's 4-3 extra-innings loss to Baltimore.

Lowe endeared himself to the Fenway Faithful by launching a game-tying, two-run home run in the bottom of the ninth inning to set up extra innings. The heroism, however, was short-lived, as the Red Sox subsequently failed to produce a run on bases-loaded situations later in the ninth, and then again in the 10th. In total, the Red Sox were 0-for-13 with runners in scoring position. Lowe's served as a pinch hitter and DH since being added to the roster Monday. Eventually, he's expected to become the primary first baseman against right-handers.

Kurtz went 3-for-3 with two doubles, one RBI, a run scored and two walks in Tuesday's win over the Twins.

Kurtz continues to terrorize opposing pitchers with another big performance. He doubled in the first inning before walking and scoring a run in the third. He later knocked an RBI double in the sixth. Kurtz has gone 48-for-112 (.429) with 26 extra-base hits over his last 30 games, raising his season slash line to .313/.399/.645 through 356 plate appearances.

Pasquantino went 2-for-3 with a solo homer, a double and two runs scored in Tuesday's win over Texas. He was also hit by a pitch.

Pasquantino ripped a solo shot in the first inning for his 24th long ball of the year. He's gone deep in back-to-back games and has five home runs over his last nine games. Pasquantino later doubled and scored the go-ahead run in the seventh inning of Tuesday's victory. The lefty slugger is now slashing .259/.320/.458 with 46 extra-base hits and 83 RBI through 124 games this season.

Manager John Schneider said Guerrero, who is out of the lineup for Tuesday's game against the Pirates, was diagnosed with left hamstring inflammation and is considered day-to-day, Keegan Matheson of MLB.com reports.

The 26-year-old suffered the injury during Monday's contest, but an MRI showed that he's avoided a serious injury. The Blue Jays have a scheduled day off Thursday, and Guerrero could be held out again Wednesday if the club chooses to play it safe with the franchise first baseman.

Guerrero (hamstring) is not in the lineup for Tuesday's game against the Pirates.

The first baseman was headed for an MRI after exiting Monday's game due to left hamstring tightness, and he'll be held out of the starting nine for at least one contest. Guerrero should continue to be considered day-to-day until the MRI results are announced.
