MLB Rumor Central: Who will attend Tim Lincecum's showcase?

Since the announcement of free-agent right-hander Tim Lincecum's pitching showcase set for this Friday, the list of teams expected to attend continues to grow.

At the time that word of Lincecum's showcase was first reported, the Baltimore Orioles, San Francisco Giants and San Diego Padres were among the estimated 20 teams expected to attend, Jon Heyman of MLB Network reported. Since then, the list has expanded to include the Los Angeles Dodgers, Oakland Athletics, Chicago White Sox, Washington Nationals and Miami Marlins, per Heyman. In addition, the Texas Rangers and Houston Astros are showing interest, as are the Chicago Cubs.

Word of the Athletics' interest in Lincecum was further confirmed by John Hickey of the Bay Area New Group. Meanwhile, another AL West team -- the Los Angeles Angels -- is "keeping tabs" on the 31-year-old and will be in attendance, Alden Gonzalez of MLB.com reports.

The Toronto Blue Jays will also have scouts there, John Lott reports.

Meanwhile, the Colorado Rockies are "unlikely" to be there, per Patrick Saunders of the Denver Post. The New York Mets are another team not expected to attend, Mike Puma of the New York Post reports.

Given Lincecum's pedigree -- two NL Cy Young Award seasons -- it's no surprise that so many teams are interested to see what the right-hander has to offer. Heyman reports that Lincecum hopes to land a starting job somewhere, although some teams, including the Giants, are looking at him as a reliever.
