Guerrero (knee) was added to the GCL Blue Jays' roster Friday to begin his rehab assignment, Sam Dykstra of MiLB.com reports.

Guerrero has been out of action since early June after straining his patella tendon. He's expected to head to Triple-A Buffalo upon the completion of his rehab assignment, raising questions about a possible major-league callup before the end of the year. The 19-year-old phenom appears to be major-league ready after hitting an incredible .407/.457./667 in 53 games for Double-A New Hampshire, but with the Blue Jays sitting 15 games out of a playoff spot, the team may prefer to keep him down in order to earn an extra year of team control.

Olson (back) will start at first base and hit fifth versus the Astros on Thursday.

Olson was held out of Wednesday's tilt due to minor back tightness but will rejoin the starting lineup for the series finale in Houston. Over 93 games this year, he's hit .240 with a .785 OPS, to go along with 19 home runs and 46 RBI.

Cron went 3-for-4 with a three-run homer Wednesday against the Tigers.

The homer, Cron's 18th of the season, provided the winning runs for the Rays, turning a 2-1 deficit into a 4-2 lead. That home-run total represents a career high for the 28-year-old, who is also setting career bests in on-base percentage (.326), slugging percentage (.475), walk rate (6.2 percent), isolated power (.212) and wRC+ (122).

Olson will be held out of Wednesday's starting lineup against Houston after suffering from minor back tightness, Susan Slusser of the San Francisco Chronicle reports.

Olson wasn't included in Wednesday's lineup as a precaution. He'll be available off the bench if needed, and he's expected to return to action in Thursday's series finale with Oakland.

Olson isn't in Wednesday's starting lineup against Houston, Jane Lee of MLB.com reports.

Olson will get just his third day off all season. He's hitting .241 with 19 home runs and 46 RBI over 92 games as the All-Star break approaches.

Olson went 2-for-4 with an RBI single and a double in an extra-innings loss to the Astros on Tuesday.

Olson's timely hit was part of a furious ninth-inning rally by the Athletics. The slugger has reached safely in all eight games of July and 10 straight contests overall, a stretch that includes six extra-base hits (four doubles, two home runs).

Dalbec went 4-for-4 with a pair of home runs and five RBI for High-A Salem in its 8-4 win over Winston-Salem on Tuesday.

Dalbec has exploded for six home runs over his last eight games, giving him a Carolina League-high 21 long balls for the campaign. The 23-year-old has proven himself as a premium power source in each of his four stops in the minors, but his swing-and-miss tendencies cast doubt on his ability to find consistent success against higher-caliber pitching. He has struck out in 30.2 percent of his plate appearances this season, which actually represents a seven-point improvement from his strikeout rate at Low-A Greenville last season.

Calhoun went 3-for-4 with a home run, two RBI, three runs scored and a walk in Tuesday's win over the Mariners.

Calhoun's solo shot in the fifth was just his sixth of the year, but third since the start of July. The 30-year-old is still recovering from a brutal start to the season and his average (.180) and OBP (.232) are unsightly as a result, but he has been turning the page of late. He's hitting .310 over eight games in July and .273 in 66 at-bats since returning from the disabled list in mid-June.

Cron went 3-for-4 with an RBI single, two doubles and a run in an extra-inning win over the Tigers on Monday.

Cron has flipped the switch since the calendar flipped to July, following a forgettable June during which he hit just .130. He's hitting .500 (10-for-20) with five doubles, a home run, five RBI, two walks and two runs over the first six games of the new month, raising his season average 17 points to .250 in the process.

Guerrero (strained patella tendon) will join Triple-A Buffalo once he is activated from the minor-league disabled list, Rob Longley of the Toronto Sun reports.

This isn't surprising, as Guerrero was reportedly days away from a promotion to Triple-A when he suffered the injury in early June. He is almost completely recovered from his injury, upping his workload in Florida over the past couple weeks, so he could join the Bisons very shortly. Naturally, this move to the highest level of the minors will lead to questions about when Guerrero could get a callup to Toronto. Offensively, he is probably ready for the majors, but there are obviously a lot of factors at play that go well beyond his readiness on the field. The Blue Jays are barely hanging around the wild-card race, and if they were willing to keep him at Double-A for 53 games while he was over 100 percent better (203 wRC+) than the average hitter in the Eastern League, it may be wishful thinking to expect them to quickly promote him from Triple-A to the big leagues, even if he gets off to an excellent start.
