Cuban second baseman Hector Olivera is considering several offers in the four- to six-year range, and the infielder could come to terms with a team this week, according to industry sources. The Dodgers, Braves, Marlins, Padres, A’s and Giants have all shown a strong interest in signing the 29-year-old, sources said.

Efren Navarro is at ease with his situation with the Angels, whatever that might be. He began to see the world different on Feb. 20, the day he lost his mentor, best friend and father, Efren Sr., after a long bout with cancer and a recent stroke.

Last year at this time, the Red Sox wondered who would replace Jacoby Ellsbury, both in the leadoff spot and in center field. But as they played against Ellsbury and the Yankees on Wednesday at George M. Steinbrenner Field, there was no longer any such wonderment.

Any player who compels you to drop everything — work, lunch, the baby (not literally) — to tune into Gameday Audio (shameless plug) and listen to him hone his craft in a Spring Training game in the far-off planet of Jupiter, Fla., is a special player, indeed. So it is with Matt Harvey.

Masahiro Tanaka is scheduled to make his first start of the year on Thursday against the Braves, and after seeing him get through all of his other hurdles without incident this spring, the Yankees have confidence about the right-hander’s health.

Yu Darvish has a partial tear of the ulnar collateral ligament in his right elbow, and although the Rangers have yet to make a final decision, all signs are pointing toward Tommy John surgery.

Spring Training action continues today, highlighted by one of the game’s best young pitchers taking the next step in his comeback process, along with a pair of marquee pitchers’ duels — one each in Arizona and Florida.

Tuesday was a promising day for the Giants bullpen, as two of their top relievers, Javier Lopez and Sergio Romo, shook off their respective injuries to make significant appearances on the mound.

Mariners ace Felix Hernandez is arguably the best right-handed pitcher in baseball. He has been for the better part of his big league career. Hernandez, however, has never pitched a meaningful game in October.

Rookies such as second baseman Joe Panik, catcher Andrew Susac, infielder Matt Duffy and right-hander Hunter Strickland contributed significantly to the Giants’ latest title. They felt relaxed and assured on the field because their older teammates kept them that way off it.

The A’s have posted a tentative travel roster for their two-game, split-squad set against the Cubs in Las Vegas, beginning Friday.

After X-rays returned inconclusive, an MRI exam on Coco Crisp’s right lower triceps revealed no structural damage on Tuesday, much to the relief of an A’s club counting on the outfielder.

The Angels will pass on Jake Locker, thank you very much. Locker, still only 26, announced his retirement from an injury-plagued career as an NFL quarterback on Tuesday. The Angels selected Locker in the 10th round of the 2009 First-Year Player Draft, signing the two-sport star for $300,000 even though he was focused primarily on football because they’d hold his rights as a baseball player until August 2015.

It was a tale of two outings yet again for A’s comeback hopeful Barry Zito, who cruised through the beginning stages of his Tuesday outing against the D-backs before losing touch of his pitches toward the end of the 2 2/3-inning performance.

Sonny Gray was ready for his first spring start Tuesday. Maybe even too ready, as the A’s likely Opening Day starter was a little amped up and had some spotty command, but overall he was pleased.

The Blue Jays were dealt a devastating blow on Tuesday afternoon when it was announced that Marcus Stroman tore the ACL in his left knee and is expected to miss the entire 2015 season.

After last week’s perfect debut, Clayton Kershaw allowed a run in his second start, on Tuesday.
